Tussockface, I genuinely didn't mean to be dismissive of what happened to your daughter, or to imply that she was daft.

I didn't go back to re-read all the previous posts in this thread properly when I came back to it, and had forgotten your experience with your daughter - I just remembered a general point being made (by Upanddown I thought!) about dehydrated ultra-athletes, and I was responding to that.

Even so, daft was the wrong word. I just meant that most people aren't taking them in such circumstances.

Didn't read thread properly, chose my words very badly and it came out totally wrong. Please accept my apologies.

Ade
